BRAKE FOR MACHINE-WAGONS.

SPECIFICATION forming partof Letters Patent No. 286,300,'dated October 9, 1833.

Application tiled August lfl, 1883. (No model.)

To all whom it may concern:

' Be it known that we, DAVID S. Hnnnvnn, IsAAc D. Hnnnnnn, and WILLIAM D. HEEB- Nnn, of Lansdale, in the county of Montgomery and State of Pennsylvania, have invented a certain new and useful Brake for Machine- Vifiagoxis, to be used as an attachment for thrashing-machines, portable engines, 850.; andwe do hereby declare the following to be a full, clear, and exact description of the-same, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

Our invention has for its object to provide improved means forlocking stationary, while in operation, the transporting-wheels of thrashing-machines, horse-powers, baling presses, portable engines, and other portable machines; and it consists in certain novel devices and combinations of parts, which we will first describe, and their point out particularly in the claims at the end of this specification.

In theaccompanyingdrawings, to which reference is made, Figure 1 represents a side elevation of a thrashing-machine having our improvement applied thereto. Fig. 2 is a bottom plan View of the same. Fig. 3 is a sectional view taken on the line a: w of Fig. 1. Fig. 4 is a sectional view taken on the line y g; of Fig. 3. Fig. '5 isa detail view, showing, particularly, the inclined bearing-faces of the brake-shoe.

Similarletters in the several figures indicate like parts.

We have shown our inventionasapplied to a thrashing-machine, and will describe it so applied; but it is evident that application of it could be made to various other machines with thesame effect.

A A represents the thrashing-machine, mounted on transporting-wheels B and O at front and rear, respectively, as shown.

Across the frame of the machine, and under the bct-tom timbers or sills thereof, we extend 'brake-beams D E, and provide such beams at opposite sides with brake-shoes F, as shown, the shoes of the brake-beam I) being adapted to cooperate with the front wheels, andthe. shoes bound and tied immovably together.

of the brake-beam E being adapted to cooperate with the hind wheels.

Diagonally through the beams D E we pass the shanks ofwhat we term clamping-bolts G G. Each of these bolts at its upper end is bent or formed with an angular projection, g, which is adapted to engage with one or another of a series of notches, 2", in a plate, 1, secured uponthe'lower timber of thethrasher, as shown, while the lower end of said bolt passes first through a thimble or boss on the .opposite side of the beam, where it is screwthreaded, and is provided with a'clampingnut, J. From this construction it will be seen that when it is desired to lock the wheels tightly, so as to steady the machine and prevent the vibration and loosening of its-parts, the angularends of the clamping-bolts are engaged with one or the other of the series of notches in the notched plates, and the clamping-nut-s are screwed tightly up until the shoes on the brake-beams are made to bear tightly upon the rims of the wheels. The brakebeams are so situated under the machine that a tightening of the bolts causes them to brace and support the middle portions of the machine, while the crowding of the brakeshoes up onto the wheels causes the rims of the latter to support directly a great proportion of the weight of the machine, and thus, in a measure, relieve the axles. To further assist in steadying the machine and holding the wheels tightly in position, we preferably incline the bearing-faces of the brake-shoes inwardly, so that when clamped to the wheels their outer portions will engage with the tire, and as the pressure is increased will tend to crowd the wheels inward upon their spindles and against the shoulders of the axles. In this way all r0 tation of the wheel, as well as any lateral sliding or rocking action of them, is prevented, and the whole support of the machine is thus To relieve the wheels from the brake-shoes it is only necessary to loosen the clamping; nuts, and then rotate the clamping-bolts until their an gular ends are disengaged from the notches in the plates and project outward, as shown by the dotted lines in Fig. 3, when the whole brake-beam and its connected parts can beremoved.

The devices for locking the front and hind wheels are constructed substantially the same;

but the latter maybe, if desired, arranged as the permanent brake contrivance of the ma: chine, to be used,when desired, in transportation from place to place, by simply providing suitable guiding loops or straps, K K, for the beam to work in, and in applying to the beam any of the ordinary lock-lever devices in common use. Of course, when so used the clamping-bolts and nuts will have to be so adjusted as to permit a limited sliding movement of the beam in its guides.

Having thus described our invention, what we claim as new is 1. As a means for locking the transportingwheels of thrashing-machines and other portable machines and engines, a locking contrivance consisting of beams extending across and under thelower timbers or sills of the machine,

' having brake-shoes for cooperating with the wheels, in combination with bolts extending diagonally from thebeams to the frame of the machine, with means applied to said bolts for forcing the beams up against the timbers or brake-beams and their shoes, the clampingbolts extending diagonally from the beams and having the angular end, the notched plates on the frame, and the clamping-nuts, the whole arranged and operating substantially as described.

4. The combinatiomwith the machine or engine and its transporting-wheels, of the brakebeams and their shoes, the notched plates on the frame, and the clamping-bolts and nuts, said bolts having the angular heads and being capable of rotation, so as to be disengaged from the notched plates, substantially as described.

5. The combination, with the machine and its supporting-Wheels, of the rear brake-beam and its shoes, the diagonal clamping-rods and their nuts, the notched plates on the frame, and the guides for the brake-beam, whereby the latter is adapted to serve as an ordinary adjustable brake for use while transporting the machine, substantially as described.
